Yet Another NUT (Network UPS Tools) Status

bsd · Post by **bsd** » Tue Jun 27, 2006 8:41 am

Hi all,

I have been using this one since long, but forget to share it with you

The tarball contains a Ruby script to collect NUT data and a graph template; put the config.rb somewhere in your /usr/local/lib/site_ruby/1.x/, and the other script in to your cacti/scripts directory, import the graph template in to your working cacti.

You will need to pass on the UPS name/id as parameter like ups0@example.com to monitor it.

Hope it is almost as useful to you as it is for me.

Cheers!

Thank you for sharing this, it works well.

I only had to change line 14 of the file "nut_ups_status.rb" to get it to work,
so it pointed to the correct config file:

Code: Select all

conf = Config::read "/etc/ups/upsd.users"

It seems like it looks something from the config, but i couln't find the location where to set it from the cacti-web-interface, so i changed it manually in the file.

Thanks again!

It trys to read password for user cacti from /etc/nut/upsd.users file; will continue even if you have not defined one. The path to upsd.users file depends on distro and, or packaging.

I had the problem that the graphs were not being generated. I simply deleted the statement "-y-grid=v" from the rrd template definition and everything worked.

Hi,

I was trying this using a Ubuntu 6.06 server with apache and cacti installed via apt (standard stuff)

I had a few little niggly issues: firstly I mis-read the original post and put the config.rb file in the wrong place (I got the config.rb and nut_ups_status.rb the wrong way around, doh!).

Importing the XML file caused some errors for me. I tracked this down the the degrees symbol not being a valid XML entity! I've removed the 2 symbols from the XML, and it imported successfully.

Once I got to the bottom of that, I still had some issues. I was getting errors in the /usr/share/cacti/site/log/poller-error.log file.

I added some configuration to my upsd.users file
---
[cacti]
password=password
allowfrom=local
upsmon slave
---
and this resolved part of the issue. The other problem was that the web server could not read the upsd.users file (not sure if this is strictly essential, but it logs an error).

Hacking slightly, I just ran this
chmod o+r /etc/nut/upsd.users

Which resolve the issue. I intend to sort out proper group permissions for this file later!

Hope this helps someone. I've attached a new zip, with the updated XML file, and a readme.txt file which details how I installed it.

Great script, really really useful, thanks for your hard work in writing this in the first place!!

Cheers,
Mark

Has anyone been able to make this work for remote UPS's

I have a number of them that I would like to graph over time.

Man ive spent days trying to get this working following every step.
First the xml issue happened to me aswell.
And other few glitches.

But eventually i was presented with emty graphs.

After much searching i checked the cacti.log

and was presented with a

"CMDPHP: Poller[0] Host[1] DS[19] WARNING: Result from CMD not valid. Partial Result:"

I have tried running the poller manually as root. This presents me with values and it starts graphing. Then i attempted to change to the user "cacti" to see if this is a permission issue. Running it as user "cacti" as per cron job also presented the graphs.

However it DOES not do so automatically from crontab.
I have the default crontab entry for cacti as follows:

*/5 * * * * cacti /usr/local/bin/php /usr/local/share/cacti/poller.php > /dev/null 2>&1

I have also tried to change the user to root in the crontab, this also does not work.

It seems it ONLY creates the graphs when the cacti poller is run manually.
This is really confusing me as i have no idea whats causing this.

YelP! ;p

Ive even tried replacing poller to cactid to see if i can get any additional info.

logs show following....

11/06/2007 10:20:01 PM - CACTID: Poller[0] Host[1] DS[19] WARNING: Result from SCRIPT not valid. Partial Result: ...
11/06/2007 10:20:01 PM - CACTID: Poller[0] Host[1] ERROR: Empty result [127.0.0.1]: 'ruby /usr/local/share/cacti/scripts/nut_ups_status.rb ups@localhost'

However running command directly as cacti user shows following....

Any luck with this? I'm getting the exact same problem.

Thanks!

I actually got the poller thing worked out, it was related to the config.rb path, but I'm still getting a broken graph (not graphing at all). Checking the apache error logs, I see this:

Code: Select all

ERROR: invalid y-grid format

I'm definitely getting data:

Code: Select all

./nut_ups_status.rb server@localhost
blvl:100 ivol:121 load:022 ovol: stat:1 temp:45.0

Here is the output from graph debug:

Any ideas as to what the problem is?

I'm getting a graph now. I edit'd the graph template and removed the 'v' from 'Unit Grid Value'. Curious if this is normal, or do I need v for useful graphs.. I guess I'll wait and see.

Thanks!

I had already removed the axis problem, so twas not the issue for me.

Mine "seems" to be some permission issue. The odest thing i tell you.
I will post a debug screen aswell from cacti soon. Just as soon as i switch that box back on. Pitty i can't get no advise on this one.

I'm having this same issue. I posted my problem in the Help Linux/Unix forums. When I run poller.php manually as the cacti user I have no issues however when I let it run out of cron it just doesn't work.

At least im not the only one!

Hope someone can find a fix..
